There are many types of stamping dies, and the dies are also classified according to the three aspects of working properties, mold structure and mold materials.
Generally can be classified according to the following main characteristics:
1. Classification according to process properties
a. Punching die: A die that separates the material along the closed or open contour line. Such as blanking die, punching die, cutting die, cutting die, trimming die, cutting die and so on.
b. Bending mold: A mold that bends the sheet blank or other blank along a straight line (bending line) to obtain a workpiece with a certain angle and shape.
c. Deep-drawing die: It is a die that makes the blank of the sheet metal into an open hollow part, or further changes the shape and size of the hollow part.
d. Forming mold: It is a mold that directly copies the blank or semi-finished workpiece according to the shape of the convex and concave molds, and the material itself only produces local plastic deformation. Such as bulging die, necking die, flaring die, undulating forming die, flanging die, shaping die, etc.
